Ship project history


Single turret breastwork monitor of somewhat obscure purpose, Glatton was intended to serve in the dual role of coast defence and attack on enemy coast defences. For the latter she was given a deep draught, for sea keeping purposes, as she would be required to accompany the fleet to sea, although this detracted somewhat from her abilities in coast defence. Conversely, her low 0.9m freeboard restricted her ability to operate in the open sea. Designed speed of 9.75kts was considerably exceeded. She handled well but was difficult to keep on a straight course.

Ship protection


2m-deep belt was 305mm amidships reducing to 254mm at the lower edge and ends and covered by 76mm deck. The breastwork had uniform 305mm walls with a 38mm deck and the turret 305mm sides and 356mm face. The magazines were protected from raking fire by a 305mm bulkhead forward below the waterline.
